AZ4U Wireless Doorbell Kit – 60 Chimes, 300 m Range, Battery-Powered Receiver

Overview

Meet the AZ4U Wireless Doorbell Kit, a flexible, battery-powered solution designed for rapid setup and reliable performance. The system ships as a compact 1 button + 1 receiver kit and is FCC certified for safe use in the USA. Its IP55 rating offers weather resistance for covered outdoor use, and its line-of-sight range reaches up to 300 meters (1000 feet), making it suitable for a wide range of living and working spaces without wiring.

Customize how you hear and see calls

With 60 selectable melodies and four volume levels (plus a mute option), you can tailor the chime to fit your environment. Distinguishing between doors or rooms becomes easier, and the blue LED ring provides a visual alert that complements the sound.

• 60 melodies let you assign different sounds to different doors or areas.
• 4 volume levels and a mute mode accommodate different times of day and noise levels.
• LED visual cue helps users in quiet environments or during late-night hours.

Simple, wire-free setup

Setup is quick and tool-free. Mount the transmitter and position the receiver anywhere with double-sided adhesive or the included screws. The transmitter runs on a small 12V battery (included as a trial) and the receiver on three AA batteries, enabling flexible placement throughout your space.

• No professional wiring or outlets required, ideal for renters and spaces with limited wiring access.
• Receiver and transmitter are battery powered for portable placement and easy relocation.
• Long-term use is supported by fresh batteries, designed for daily reliability.

Expandability and real-world uses

This system can grow with your needs. Add more transmitters or receivers to cover additional doors, rooms, or offices, while keeping all units paired to minimize interference in multi-unit homes.

Beyond a front door bell, use cases include a caregiver call button, kitchen timer bell, kids room alert, or classroom notification system. The sleek white unit with a blue LED ring blends with most interiors and sits neatly on a shelf or wall mount. Available in white and black to match your decor, the compact receiver remains unobtrusive at entrances.
